SEM investigation of polishing composite restorations

Abstract

Proper finishing and polishing of composite restaurations are procedures that enhance the quality of restorations and reduce plaque accumulation. The purpose of this study was to evaluate with SEM analysis the effect of different polishing methods and instruments of composite surface after polishing. We used different instruments for finishing and polishing: carbide tungsten burs, diamond fissural burs, steel fissural burs, Lo-Flex Pop On discs, Sof-Lex Pop On discs, Hawe rubber cups, gray rubber cups, green rubber cups, polishing strips, polishing pastes. The results we obtained showed that the most efficient polishing of composite restorations was achieved after treatment with Sof-Lex discs, rubber cups and pastes. Treatment with carbide tungsten burs, was the least effective, producing the lowest smoothness of composite surface.

Pravilna definitivna obrada kompozitnih ispuna obezbeđuje kvalitetne restauracije i znatno smanjuje akumulaciju plaka na njima. Cilj ovog istraživanja je bio da se SEM-om ispita efekat različitih tehnika za poliranje na površinu kompozita tokom definitivne obrade ispuna. Ispitivani su različiti rotirajući instrumenti i sredstva za finiranje i poliranje: tungsten karbidna svrdla, dijamantska fisurna svrdla, čelična fisurna svrdla, Lo-Flex Pop On diskovi, Sof-Lex Pop On diskovi, Hawe gumice, sive i zelene gumice, polirajuće trake i paste za poliranje. Dobijeni rezultati su pokazali da je najkvalitetnija definitivna obrada kompozitnih ispuna ostvarena posle primene Sof-Lex diskova u kombinaciji sa polirajućim gumicama i pastama, a najmanje efikasna pri obradi istih tungsten karbidnim svrdlima.
